It was as expected I got it for 25lb of boost running E65 on a 1.4T. It reads fairly accurate for expected values. Little bit on crimping or soldering connections you install but ultimately it works well, goes through set up quickly, and hasn’t had any issues in the first month of use. Product arrives as expected.

As always AEM has come through with another amazing product. The new bosch LSU 4.9 sensors are blazing fast and have better accuracy as well. This is a great gauge and I highly recommend them to everyone and anyone who needs a wideband. Great company hands down the best wideband on the market in my opinion.

Packaged very well, great instructions that aren't broken English lol. Installed easy. It came with a sensor bung (I already had an empty sensor bung in my exhaust), PLENTY of wire harness for the sensor and more than enough for the gauge. Several gauge face options as well.

this is a nice afr guage that comes with everything you need to install it. It does have a weld in bung for the o2 sensor that is required, but i purchased a strap on bung that only requires drilling of the pipe to install and it works great.

I used a unit identical to this one to monitor the AFR on my steam powered Bonneville Streamliner, and it gave such excellent performance and dependability that I bought this second one to be used on another project that I’m building.

Exactly as described. New style Bosch o2 sensor seems to be a bit more accurate. Also has a light exposure "eye" that adjusts the display brightness so its not blinding at night or dim in the sun. AEM has always treated me right.

Brand new in box. I have bought this item before from rally sport for my STI this came in faster and for less. Granted the sensor was DOA but the seller sent out a replacement ASAP with a return box. Everything worked out well.

The gauge was as described. The readings are very fast (maybe 8 samples per second). A quality product. Be sure to read the supplied docs as the meter must be under power on a running engine so the unit is not damaged.
